**Purpose**: If you run an environment with multiple Hyper-V: Failover Clusters, for the purpose of Hyper-V: Failover Cluster Replication via a `Hyper-V Replica Broker` role installed on a host within the Failover Cluster, sometimes a GuestVM will fail to replicate itself to the replica cluster, and in those cases, it may not be able to recover on its own. This guide attempts to outline the process to rebuild replication for GuestVMs on a one-by-one basis.

|
!!! note "Assumptions"
|
|
This guide assumes you have two Hyper-V Failover Clusters, for the sake of the guide, we will refer to the Production cluster as `CLUSTER-01` and the Replication cluster as `CLUSTER-02`. This guide also assumes that Replication was set up beforehand, and does not include instructions on how to deploy a Replica Broker (at this time).

|
|
## Production Cluster - CLUSTER-01
|
|
### Locate the GuestVM
|
|
You need to start by locating the GuestVM in the Production cluster, CLUSTER-01. You will know you found the VM if the "Replication Health" is either `Unhealthy`, `Warning`, or `Critical`.
|
|
### Remove Replication from GuestVM
|
|
- Within a node of the Hyper-V: Failover Cluster Manager
|
|
- Right-Click the GuestVM
|
|
- Navigate to "**Replication > Remove Replication**"
|
|
- Confirm the removal by clicking the "**Yes**" button. You will know if it removed replication when the "Replication State" of the GuestVM is `Not enabled`
|
|
|
|
## Replication Cluster - CLUSTER-02
|
|
### Delete the GuestVM from Replication Cluster
|
|
- Within a node of the replication cluster's Hyper-V: Failover Cluster Manager
|
|
- Right-Click the same GuestVM and click "Manage..." `This will open Hyper-V Manager`
|
|
- Right-Click the GuestVM and click "Settings..."
|
|
- Navigate to "**ISCSI Controller**"
|
|
- Click on one of the Virtual Disks attached to the replica VM, and note the full folder path for later. e.g. `C:\ClusterStorage\Volume1\HYPER-V REPLICA\VIRTUAL HARD DISKS\020C9A30-EB02-41F3-8D8B-3561C4521182`
|
|
|
|
!!! warning "GUID Identification"
|
|
You need to note the folder location so you have the GUID. Without the GUID, cleaning up the old storage associated with the GuestVM replica files will be much more difficult / time-consuming. Note it down somewhere safe, and reference it later in this guide.
|
|
|
|
Delete the GuestVM manually from Hyper-V Manager on Host-05, Host-06, Host-07, Host-08)
|
|
Delete the GuestVM's replicated VHDX storage from replication storage on C:\ClusterStorage\Volume02
|
|
Enable Replication on GuestVM in Cluster-01 (Production Cluster) |
